Problems solved by technology

In some instances, the two radio interfaces in the UE may create interference with each other.
For example, the active transmission of the first radio interface may create interference that reduces the receiver performance of the second radio interface.
This type of interference may be severe when the two radio interfaces are operating within the same frequency band.
Even if they are operating in different bands, the interference may still be significant if they are operating in certain band combinations.

Embodiment Construction

[0024]The present disclosure is directed to dynamically managing band capability. As previously mentioned, DSDA-capable UEs may communicate with two RANs at the same time, so the UE may manage its band capability to prevent or otherwise reduce interference between two RF channels. In some implementations, the UE may manage the band capability statically. For example, the UE may divide the supported frequency bands into non-overlapping subsets. In these instances, each subset includes the frequency bands that do not interfere with the frequency bands in other subsets. The UE reports the non-overlapping subsets to the RANs, and, consequently, communicate with RANs on the RF channels within the frequency bands in one subset. Two different RANs may select RF channels that do not interfere with each other based on the reported non-overlapping subsets.

[0025]Alternatively or in combination, a UE may manage band capability dynamically. FIG. 1 is a schematic illustrating an example mobile co...

Abstract

In some implementations, a method in a user equipment (UE) for dynamically managing band capacity includes communicating with a first radio access network (RAN) on a first Radio Frequency (RF) channel and a second RAN on a second RF channel, where the first RAN and the second RAN are different networks. The UE receives an indication from the first RAN (or makes a determination) to handover to a third RF channel. The UE determines that the third RF channel conflicts with the second RF channel. The UE disables an RF band including the second RF channel with the second RAN and reports updated RF Band Capabilities to one or both RANs.

Description

CLAIM OF PRIORITY[0001]This application claims priority under 35 USC §119 to European Patent Application No. 14305351.0, filed on Mar. 11, 2014, the entire contents of which are hereby incorporated by reference.TECHNICAL FIELD[0002]This invention relates to dynamically managing band capability.BACKGROUND[0003]A Dual SIM Dual Active (DSDA) capable user equipment (UE) may access two Radio Access Networks (RANs) at the same time. For example, the UE may enter into an active (or connected) state with a first RAN and communicate with the first RAN using a first radio interface. At the same time, the UE may enter into an active (or connected) state with a second RAN and communicate with the second RAN using a second radio interface. In some instances, the two radio interfaces in the UE may create interference with each other. For example, the active transmission of the first radio interface may create interference that reduces the receiver performance of the second radio interface. This t...
